This is a handy tool to help students learn about and analyze geometric shapes, congruence, similarity and symmetry. The mirror is made of reflective, transparent red plastic. 0-12 centimeters is marked on one edge, and the opposite edge is marked 0-5 inches. One end is cut straight, and the other end is curved for drawing and measuring. Each mirror comes with one ruler/protractor template and one reflective enhancer card. There is a built-in support which will hold the template and/or reflective enhancer card. The Math VU Mirror is designed to work with the Investigate & Discover Geometry, Shape, Space & Measurement series. ~ Donna
Grades 4-6, junior, will cover lines, angles, segments, symmetry, triangles, quadrilaterals and motion geometry. Students use the mirror at this level to connect lines, measure angles and find lines of symmetry in quadrilaterals.
Grades 7-9, intermediate, reinforces and teaches construction applications in triangles, congruency, symmetry, polygons, motion geometry. The Math VU mirror is used to do more challenging problems at this level.
Each book begins with an explanation of how to use the Math VU mirror and ends with a tracking sheet for the student. This allows you to keep up with your child’s success record. Each exercise has easy-to-follow instructions and could probably be completed with little adult interaction. There are between 45 and 50 exercises in each book; pages are reproducible for classroom or family use. I’ve never seen anything quite like this program, but I have had a lot of fun trying it out. The Math VU mirror and Investigate & Discover Geometry series would be an interesting addition to any math program. ~ Donna
